very nice posts LBSS.
as for training with soreness, it depends on the goal of the session etc..
Recovery sessions can help to "mask" the intensity of DOMS or actually improve it:
- Sled dragging (great for alleviating soreness)
- Light active-dynamic work, any type of activity that is submax and greatly improves blood flow (light sport practice, light interval sprints)
- High rep lifting, 15-20 reps, light.. not 20 rep squats
Strength sessions can be performed with DOMS:
- ME & RE sessions can be performed, just make sure a thorough warmup is performed and foam rolling and/or stretching follows the lifts, because fascia can become "tighter" when lifting with soreness
Should not be performed with "considerable soreness":
- Peak performance sessions (max effort MAX V sprints, full runup RVJ's, depth jumps/single leg bounds/shock)
- Peak RFD work
When it comes to jumping, in my experience:
- max effort jumping with considerable quad soreness is very dangerous, can really leave you with some knee aches and possibly worse.. NEVER jump with considerable VMO soreness.
- ME jumping with hamstring soreness tends to make me jump lower but the sessions are bearable
- ME jumping with glute soreness is interesting, sometimes I get up even higher when my glutes have a small bit of soreness, but when they are considerably sore, they can actually "pull" very easily
- ME jumping with considerable calf soreness is dangerous, puts too much strain on the achilles
- ME jumping with upper body soreness depends, usually doesn't impact much
When it comes to sprinting, in my experience:
- max effort MAX-V sprinting should be avoided completely if you have: considerable hip flexor (illiopsoas), ham string, or quad soreness.. Hip flexor/hamstring soreness can easily lead to pulls, quad soreness can easily lead to patellar aches & pains due to possibly less optimal firing of vmo.
- max effort short accels (10-20m) should still be avoided if there's considerable soreness in the above muscle groups, but it's much less risky given the lower velocity's obtained.
- glute soreness isn't much of an issue, though speed can decrease, risk of injury to glutes and joints doesn't seem to be that high with glute soreness.
